So I was thinking of putting my Large egyptian bowl after it has been packed and foiled, and stick it in the freezer for 10-15 minutes. Should make it a cooler smoke. This is along with putting the hookah stem and base in the freezer to and then adding ice to the water. What does everyone think?

same idea as the ice bowl (its a small bowl that has a chamber around it to fill with water and freeze) to get the shisha going it has to heat up enough so its kind of pointless to try and keep the shisha cool when it has to get hot to smoke.

To make smoke the shisha has to be at a temperature well above your freezer. By lowering the temperature, you would just be delaying the start of the smoking.
Cooling the stem, and vase works because it is after the smoke has been produced

I don't think it would work because after you put on the coals and start drawing you will bring the bowl back up to normal operating temperatures thus just making your idea pointless. The only notable change would be that it will take you longer to get the bowl going

It will be great when it heats up and expands.It will stay cold for half a minute. Ibought once a specially made for freezer bowl. It has a chamber inside for quite a bit of water. The first one burst in the freezer and the replacement sent to me cracked while smoking. The water melted in no time.
